Answer:
<em>D. 51</em>
Step-by-step explanation:
First we find the number of 8th graders.
34% of 600 = 34% * 600 = 0.34 * 600 = 204
There are 204 8th graders.
One-fourth of 204 students walk to school.
We need to find one-fourth of 204.
1/4 * 204 = 1/4 * 204/1 = 204/4 = 51
Answer: D. 51
600 * .34 = 204 are in 8th grade
204 * 1/4 = 51 51 8th graders walk to school
